The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report
The Cape Sable Seaside Sparrow (Ammodramus maritimus mirabilis) was listed as an original member of the federal list of endangered species in 1968. It is restricted to seasonally flooded prairies of extreme southern Florida and is disjunct from all other conspecific breeding populations (Kushlan et al 1982, McDonald 1988). Since the subspecies was described in 1919, its populations have...

Contaminant effect endpoints in terrestrial vertebrates at and above the individual level Contaminant effect endpoints in terrestrial vertebrates at and above the individual level
Use of biochemical, physiological, anatomical, reproductive and behavioral characteristics of wild terrestrial vertebrates to assess contaminant exposure and effects has become commonplace over the past 3 decades. At the level of the individual organism, response patterns have been associated with and sometimes causally linked to contaminant exposure. However, such responses at the...

Recreation impacts and management in wilderness: A state-of-knowledge review Recreation impacts and management in wilderness: A state-of-knowledge review
This paper reviews the body of literature on recreation resource impacts and their management in the United States, with a primary focus on research within designated wildernesses during the past 15 years since the previous review (Cole 1987b). Recreation impacts have become a salient issue among wilderness scientists, managers and advocates alike. Studies of recreation impacts, referred...

Landscape associations of frog and toad species in Iowa and Wisconsin, U.S.A Landscape associations of frog and toad species in Iowa and Wisconsin, U.S.A
Landscape habitat associations of frogs and toads in Iowa and Wisconsin were tested to determine whether they support or refute previous general habitat classifications. We examined which Midwestern species shared similar habitats to see if these associations were consistent across large geographic areas (states). Rana sylvatica (wood frog), Hyla versicolor (eastern gray treefrog)...

Managing wetlands for waterbirds: How managers can make a difference in improving habitat to support a North American Bird Conservation Plan Managing wetlands for waterbirds: How managers can make a difference in improving habitat to support a North American Bird Conservation Plan
Wetlands are the most productive ecosystems in the world, yet they have suffered more loss and degradation than any other ecosystem. Not surprisingly, 50% (29 of 58) of all the bird species in the U. S. (excluding Hawaii and territories) that are listed either as federally threatened or endangered, or are on the U. S. Fish & Wildlife Service 1995 List of Migratory Nongame Birds of...

Grassland birds: An overview of threats and recommended management strategies Grassland birds: An overview of threats and recommended management strategies
Grassland ecosystems are dependent on periodic disturbance for habitat maintenance. Historically, grazing by native herbivores and prairie fires were the agents principally responsible for maintaining grassland areas. However, elimination of native herbivores, wide-spread fire suppression, and conversion for agriculture have greatly altered grasslands in the United States and Canada...

Combining information from monitoring programs: Complications associated with indices and geographic scale Combining information from monitoring programs: Complications associated with indices and geographic scale
To adequately monitor Neotropical migratory birds, information must be collected to assess population change at local, regional, and continent-wide scales. I suggest that large-scale survey results (such as those derived from the North American Breeding Bird Survey) should not be used to predict population attributes on parks, refuges, and other protected areas. These areas are often...
